This may be influenced by the wave of populist nationalism but it again may also be a reaction to the reality that there isn't just one hegemony pulling the strings anymore (the US, or the west in general). Especially if said hegemony is acting unpredictable and other countries are now acting belligerent. That seems like a self-reinforcing cycle. I'm sure there's more reasons beyond these
